Sandvik Coromant 5908965 Turning Insert CNGG433-SGF

Product Description

The SANDVIK COROMANT 5908965 is a solid carbide turning insert in the CNGG style, designed for precision metal cutting in CNC lathe and turning center applications. Carrying the 1105 grade with a PVD-applied TiAlN coating, this insert delivers strong wear resistance and thermal stability when machining stainless steel, superalloys, and titanium. The 80-degree diamond shape (Insert Shape Code C) provides a sturdy cutting geometry, while the SGF chip breaker promotes controlled chip evacuation in finishing and semi-finishing passes. With a 0.5 inch inscribed circle and a 3/64 inch corner radius, it suits applications where edge integrity and dimensional accuracy are critical. Neutral hand orientation makes it adaptable to standard toolholders without handed restrictions.

This insert is suited for use in production turning environments machining difficult-to-cut materials including austenitic stainless steels, nickel-based superalloys, and titanium alloys. It belongs to the Sandvik Coromant T-Max P series, engineered for external and internal turning operations on CNC equipment. Typical installers are CNC machinists and tooling technicians working in aerospace, medical device, oil and gas, and general precision manufacturing shops.

Key Features

• Solid carbide construction with PVD TiAlN coating for heat and wear resistance in demanding alloys
• SGF chip breaker geometry optimized for finishing and light semi-finishing cuts
• 80-degree diamond insert shape (CNGG style) with neutral hand for versatile toolholder compatibility
• 3/64 inch (0.0469 inch) corner radius for controlled edge engagement and surface finish
• 4 available cutting edges per insert for extended tooling value
• ISO designation CNGG120412-SGF 1105 for cross-reference with international toolholder catalogs

Compatibility

Designed for use with toolholders accepting CNGG-style inserts within the Sandvik Coromant T-Max P series. Compatible with primary workpiece materials coded M (stainless steel) and secondary materials coded S (superalloy and titanium). Verify toolholder seat size against the 0.5 inch inscribed circle and 3/16 inch insert thickness before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified CNC machinist or tooling technician with the machine in a locked-out, de-energized state per applicable lockout/tagout procedures. Ensure the toolholder pocket and clamp seat are clean and free of chips before seating the insert. Use the specified clamp and pin holding method to secure the insert; do not over-torque the clamp screw beyond the toolholder manufacturer's specification. Inspect the cutting edge for chips or cracks before each use and index or replace as needed.
